BEST MODE FOR CARRYING OUT THE INVENTION

The object of the present invention is accomplished by a bed for patient having a bedpan means installed on the lower part of the bed, the bed supporting a mattress thereon. An opening is formed on the upper part of a portion of the bed having the bedpan means installed, and a shield means for shielding the hip and the private parts of a patient is installed on a side of the opening.

The present invention will now be described in detail in connection with preferred embodiments with reference to the accompanying drawings.

FIG. 1 shows a structure of a bed for patient according to the present invention.

As will be seen from FIG. 1, the bed for patient comprises a bedpan means 300. A shield means 500 for shielding the hip and the private parts of a patient is installed on the upper part of the bedpan means 300.

The bed for patient further comprises 100, a disrobing means 200 and a control box 400.

The bedstead 100 includes a mattress 110, a mattress supporting frame 130 and a mattress folding means 120. As shown in FIG. 3 6, the mattress 110 includes a back part 111, a hip supporting part 112, a leg supporting part 113 and a foot supporting part 114. All of the parts are foldably joined with a hinge.

The back part 111 and the hip supporting part 112 of the mattress 110 are rotatably inserted in a hinge hole through a fixed hinge axis 111 a, the hinge hole being formed on the inside of a vertical frame 133 of frames making up the mattress supporting frame 130.

Thus, the back part 111 and the hip supporting part 112 is folded centering around the hinge axis 111 a as shown in FIGS. 3 and 6, or is spread as shown in FIG. 4.

Portions between the hip supporting part 112 and the leg supporting part 113, and the leg supporting part 113 and the foot supporting part 114 are foldably connected through folding means 112 b and 114 a. That is, when a patient is in a position for easing nature, as shown in FIG. 3, the folding means 112 b is lifted up, and the hip supporting part 112 is tilted in right upward direction and the leg supporting part 113 is tilted in right downward direction in figure to support comfortably the fleshy inside of the thigh and the calf. Further, the folding means 114 a is lifted down, and the foot supporting part 114 and the leg supporting part 113 is tilted with an angle similar to that of the foot of patient.

As will be seen from FIG. 3, a moveable hinge axis 113 a installed on the leg supporting part 113 is positioned on a portion inclined to the folding means 114 a, that is the middle of the leg supporting part 113. Thus, the height of the folding means 112 b is equal to the height of the end of the foot supporting part 114 to support and lift up the middle and one end of a trousers hanger transporting frame 210 at the same time.

Moveable hinge axes 113 a and 114 b are installed on the middle of the leg supporting part 113 and one end of the foot supporting part 114, respectively.

As shown in figures, each part of the mattress 110 is tilted to comfort a patient for easing nature, as the moveable hinge axes 113 a and 114 b are inserted and laterally moved in the inside of axes moving grooves 133 a and 133 b formed in the inside of the vertical frame 133 of the mattress supporting frame 130.

A mattress folding means 120 for folding the mattress 110 is installed in order to comfort the patient for easing nature.

As shown in FIG. 2, the mattress folding means 120 is comprised of two cylinders 121 and 122.

The first cylinder 121 of two cylinders 121 and 122 is the means for lifting-up and down the back part 111 of the mattress 110 in order to make the patient sit up against the back part. One end of the first cylinder is rotatably connected to any one of the frames constituting the mattress supporting frame 130, and a piston axis reciprocating in the first cylinder is rotatably connected to a middle portion of the back part 111 through a hinge plate 123.

The second cylinder 122 is the means for folding the hip supporting part 112 centering on the fixed hinge axis 111 a. The structure of the second cylinder is the same as that of the first cylinder 121.

As shown in FIG. 2, other devices are easily installed on the center of the bedstead 100, as the first and the second cylinders 121 and 122 are installed on portions adjacent to the vertical frame 133, respectively.

A bedpan opening 112 a is formed on the center of the hip supporting part 110 in the mattress 110, and a bedpan 310 is installed under the bedpan opening 112 a.

As will be described later, the bedpan 310 is connected to a discharging means 340 to discharge a wastewater having dejection in the bedpan 310.

As shown in FIGS. 3 and 4, one port of 3-way valve 343 is connected to a drainpipe connected to the lower part of the bedpan 310, and the remaining two ports are connected to two pipes, one connected to a wastewater container 341 and the other 342 connected to an outfall.

As shown in FIGS. 8 and 9, the wastewater container 341 has double walls formed by two containers.

The wastewater container 341 is comprised of an outer protecting container 341 a and an inner creased container 341 b. The outer protecting container 341 a is made of a metal or plastics which is not contorted or damaged by an external force. A groove 341 g is formed on the surface of the outer protecting container.

Further, numbers of wheels are installed on the lower part of the outer protecting container 341 a to move the container easily.

The inner creased container 341 b installed in the inside of the outer protecting container 341 a is provided with an inflow pipe 341 d and an outflow pipe 341 c, and also provided with a moving plate 341 e on one end thereof. A grip 341 f is formed on the moving plate 341 e, the grip being protruded to the outside through the groove 341 g formed on the surface of the outer protecting container

As shown in the figure, the inner creased container 341 b has numbers of creases. The inner creased container is shrunk when the container is not filled with a substance, and is extended when the container is filled with a substance. As the inside of the inner creased container is shut from the outside, a bad smell from the substance is prevented from being leaked to the outside.

When the wastewater container 341 is filled with an evacuation, the wastewater container is moved to a place for discharging the evacuation, and then the moving plate 341 f formed on one end of the inner creased container 341 b is pushed toward the outflow pipe 341 c to discharge the evacuation filled in the inner creased container 341 b.

That is to say, the evacuation in the inner creased container is discharged by inclining downwardly the outflow pipe 341 c, and pushing the grip 341 f toward the outflow pipe 341 c to shrink the inner creased container 341 b.

A water-supply pipe 321, which supplies washing water for flushing the evacuation in the bedpan, is connected to one end of the bedpan 310. The water-supply pipe 321 is normally connected to water supply facilities, and is provided with an electronic valve on the middle thereof to perform automatically water-supply.

The electronic valve(not shown) installed on the water-supply pipe 321 is automatically opened/closed by a sensor(not shown) installed a side of the bedpan 310, the sensor sensing an evacuation. The electronic valve is controlled by the control box 400.

An opening/closing means 330 for opening/shutting the bedpan opening 112 a formed in the hip supporting part 112 of the mattress 110 is installed on the upper part of the bedpan 310.

As shown in FIG. 7, the opening/closing means 330 includes a bedpan cover 331 and a driving means for moving the bedpan cover.

A couple of projections 337 are formed on both sides of the bedpan cover 331, respectively, and a hinge rod 336 is formed on an end of the bedpan cover in moving direction. The bedpan cover 331 is moved toward lateral-upward direction or lateral-downward direction by pushing or puling laterally the hinge rod to open/close the bedpan opening 112 a formed in the hip supporting part 112.

As shown in FIG. 7, a protrusion is formed on the upper surface of the bedpan cover 331, and is opposed to the bedpan opening 112 a formed in the hip supporting part 12 of the mattress 110.

A connecting rod 335 is rotatably connected to the hinge rod 336 formed on the bedpan cover 331. The connecting rod 335 is also rotatably connected to a motor 332.

The motor 332 is a driving source for opening/closing the bedpan cover 331, and is provided with a pinion 333 on a rotating axis thereof.

Teeth formed in the pinion 333 are engaged with teeth formed in a rack 334 under the pinion. When the pinion 333 is rotated by driving the motor 332, the pinion 333 is moved along the rack 334 to move the motor 332, and the connecting rod 335 rotatably coupled to the motor 332 is also moved.

The movement of the connecting rod 335 according to the movement of the motor 332 transfers the bedpan cover 331 laterally.

In order to facilitate the movement of the bedpan cover 331, that is not only horizontal movement of the bedpan cover but also diagonal movement of the bedpan, a guide 338, which guides the projections 337 formed on the both sides of the bedpan 331, is further installed. The guide 338 is provided with guide grooves 338 a and 338 b thereon, in which the projection 337 is moveable. As shown in figure, the projection in the guide grooves 338 a and 338 b are moved from the horizon to the diagonal, or vice versa.

As described above, the bed for patient according to the present invention is provided with the disrobing means 200 which help a patient, who is paralyzed from waist down, to get into or put off clothes.

One embodiment of the disrobing means 200 is FIG. 10 FIG. 12.

As shown in figures, the disrobing means 200 includes tongs-shaped trousers hanger 212 shaped for picking up trousers, a trousers hanger transporting frame 210 for moving the trousers hanger 212 along stature direction, and a frame supporting means 220 for moving the trousers hanger transporting frame 210.

The trousers hanger transporting frame 210 is respectively positioned on both end of the mattress supporting frame 130 along the stature direction, and extended from the waist of the patient to the foot.

As cross-sectionally shown in FIG. 10, a trousers hanger moving hole 211 is formed in a portion of the trousers hanger transporting frame 210 toward the mattress, and a motor 214 is installed in the inside of one end portion toward the foot of the patient. The axis of rotation of a bevel gear, which is engaged with the axis of rotation of a bevel gear 214 a installed on a shaft of the motor 214, is provided with a pulley 215.

A pulley 215 is installed in the inside of the other end opposed to the one end having the pulley 215. A trousers hanger transporting belt 216 is suspended between the pulleys 215 and 215.

One end of a connection string 213 having the trouser hanger 212 on the other end is fixed to the trousers hanger transporting belt 216. Stop switches 217 and 217, which limit a moving distance of the trousers hanger 212, are installed in a portion of the inside of the trousers hanger transporting frame between the two pulleys 215 and 215. As the connection string 213 is touched to the switches, electricity supplied to the motor 214 is cut off to stop the movement of the motor.

As described above, the trousers hanger transporting frame 210 is supported by the frame supporting means 220. When the frame supporting means 220 supports the trousers hanger transporting frame 210, the trousers hanger transporting frame is supported to move toward a patient lain down the bed. In order for this, a means for moving the trousers hanger transporting frame 210 to the patient is installed in the inside of the frame supporting means 220.

The frame supporting means 220 is constructed as shown in FIG. 11.

The means for moving the trousers hanger transporting frame 210 is formed by suspending a frame transporting belt 260 between two pulleys 231 and 231. The frame transporting belt 260 is rotated by rotating any one of pulleys 231 to move the trousers hanger transporting frame 220 fixed on the frame transporting belt 260.

A means for driving the pulley 231 is the motor 230. The motor 230 is driven by operating control buttons(not shown) on the control box 400.

Further, a movement of the trousers hanger transporting frame 210 is stopped by operation of a stop switch 234 mounted on the inside of the frame supporting means 220.

That is to say, as the trousers hanger transporting frame 210 is enough moved, a portion of the frame transporting belt 260 on which the trousers hanger transporting frame 210 is fixed pushes the stop switch 234 to cut off electricity supplied to the motor 230.

Further, a moving-up and down axis 240 is installed on the lower part of the frame supporting means 220. The moving-up and down axis 240 is inserted in a moving-axis supporting frame 250 fixed on an edge supporting frame 131 to move the frame supporting means 220 up and down.

Namely, as a patient is leaned against and laid on the bed for evacuation to rise, the moving-up and down axis 240 is extracted from the moving-axis supporting frame 250 to raise the frame supporting means 220, thereby raising the trousers hanger transporting frame 210 to prevent the patient from being touched to the trousers hanger transporting frame 210.

A water-supply means 320 is mounted on a side of the bedpan 310.

The water-supply means 310 is for washing the hip and the private parts of the patient after evacuating, and is integral with the shield means.

The first embodiment of the shield means 500 is shown in FIGS. 13 18 in detail.

The shield means 500 in FIG. 13 is the shield means having not a water-supply means. The shield means includes a housing 351 which is hollowed and is arc-shaped in a vertical section and a cross section, and a shielding piece 353 which has the same arc-shape as that of the housing 351 and is installed in the housing.

The shielding piece 353 is formed with integral different from a shielding piece in FIG. 14. As shown in FIG. 13, the shielding piece 353 shields around the private parts when extracted from the housing 351 because the shielding piece is arc-shaped in the vertical section and the cross section.

The second embodiment of the shield means 500 is shown in FIG. 14. The shield means includes the housing 351 enclosing each of elements, a shielding piece housing 352 having shielding pieces 353 for shielding the private parts therein, a shielding piece driving means 358 for extending the pieces 353, and a moving means 356 for extracting the shielding piece housing 352 from the housing 351.

As shown in FIGS. 3 and 4, the housing 351 is fixed to a side of the mattress supporting frame 130 through a housing fixing frame 370, and is rotated with its hinge point as the central figure by operation of a spring shock absorber 360. The housing is formed as a tube-type with an arc shape. As shown in FIG. 14, an insertion groove 351 a for a water-supply pipe is formed on an inner side of the arc shape. As will be seen from FIGS. 14 to 16, an arc-shaped rack 351 b is installed on the inside of the housing, and a pinion 354 a mounted on the axis of rotation of a D.C. motor 354 is engaged with the rack 351 b.

The inside of one end of the housing 351, that is, the inside of the end opposing to the shielding piece housing 352 is provided with a step, and a housing step 352 b formed on the shielding piece housing 352 is caught by the step in the housing 352.

As described above, the shielding piece housing 352 is installed in the inside of the housing 351 to freely come in and out the housing 351.

The shielding piece housing 352 includes two arc-shaped plates, and each of the plates has curvature for inserting into the inside of the housing 351. The end of the shielding piece housing toward the housing 351 has the housing step 352 b which is caught by the step formed on the housing 351. A water-supply pipe insertion part 352 a, which has numbers of passing-through holes and is opposed to the insertion groove for water-supply pipe 351 a formed in the housing 351, is formed on the housing 352 with integral.

As shown in FIG. 14, the insertion groove for water-supply pipe 351 a has a portion which is incised towards the exterior, and is formed such that the water-supply pipe insertion part 352 a formed on the shielding piece housing 352 is moveable along the insertion groove for water-supply pipe 351 a with being inserted into the insertion groove for water-supply pipe 351 a.

So to speak, a hose 352 d inserted in the water-supply pipe insertion part 352 a formed on the shielding piece housing 352 is moveable along the portion, incised toward the exterior, of the insertion groove for water-supply pipe 351 a. In order for movement of the hose 352 d, the hose is made of soft plastics.

The shielding piece 353 is hinge-fixed to a hinge-projection 353 a formed on both sides of the shielding piece housing 352, and is normally in a folded state toward the center of the housing 352 by means of a spring 353 b. A rotating projection part 353 c is formed on the hinge-fixed portion.

Namely, as shown in FIG. 16, when the shielding piece housing 352 is in the housing 351, the shielding piece 353 is inserted in the shielding piece housing 352 to be hidden. As shown in FIG. 15, when the shielding piece housing 352 is out of the housing 351, the shielding piece 353 is spread out from the shielding piece housing 352 to shield the hip and the private parts of patient.

As will be seen from FIGS. 17 and 18, the passing-through hole formed on the water-supply pipe insertion part 352 a is formed as a cylinder-type and has numbers of holes formed thereon. An injection nozzle 440 is formed on the holes.

The hose 352 d in the water-supply pipe insertion part 352 a is connected to one end of the injection nozzle 440, and the injection nozzle 440 is rotatably installed by a rotating axis 442. A means for controlling a direction of injected air and water is further provided. The direction of the injected air and water is controlled by repeatedly rotating the injection nozzle 440 to change a direction of an injection hole 441.

The means for controlling the direction of injected air and water is formed by installing an eccentric pulley 420 on the axis of rotation of a D.C. motor 410, and connecting a wire 430 to a side of the cylindrical injection nozzle 440. Therefore, the means for controlling the direction of injected air and water is rotated, as the eccentric pulley 420 is rotated by the D.C. motor.

The D.C. motor 354, the pinion 354 a and the rack 351 b are provided as a means for pushing or drawing the shielding piece housing 352 into or from the housing 351.

The moving means 356 is installed on a circumference of the D.C. motor 354. As shown in FIGS. 15 and 16, the moving means 356 is installed in the housing 351, and is moved by operation of the motor 354 in the housing.

That is, when the pinion 354 a installed on the axis of rotation of the D.C. motor 354 is rotated by operation of the motor 354, the motor 354 is moved as the pinion is engaged with the rack 351 b fixed on the inside of the housing 352. Thus, the moving means 356 is transferred to move the driving plate 358 connected to a side of the moving means 356.

A second shock-absorbing spring 356 a is installed on the inside of the moving means 356.

As described above, one end of the shielding piece driving plate 358 is inserted in the moving means 356. The shielding piece driving plate 358 pushes the rotating projection part 353 c formed on a side of the shielding piece 353 to rotate the shielding piece 353 with the hinge axis 353 a as the central figure. Thus, the shielding piece 353 is exposed from the shielding piece housing 352 as shown in FIG. 15 a.

The shielding piece driving plate 358 is shaped as a plate-type, and provided with a shielding-piece rotating means 358 c on both sides thereof. The shielding piece driving plate pushes the rotating projection part 353 c formed on the hinge-fixed portion of the shielding piece 353 to spread out the shielding piece 353 from the shielding piece housing 352. One end of the shielding piece driving plate 358 is inserted into the moving means 356 to be elastically supported by the second shock-absorbing spring 356 a.

A first shock-absorbing spring 355 is further installed between the moving means 356 and the end of the shielding piece housing 352 inserted in the housing 351.

As the first shock-absorbing spring 355 is shrunk when the shielding piece housing 352 is caught by a part of patient body or a sheet, one end of the moving means 356 pushes a stop switch 357 installed on the housing 351 to stop the D.C. motor 354. Thereby, the patient is not irritated by the shielding piece housing 352.

As shown in FIGS. 2 and 3, when the housing 351 is fixed by the housing fixing frame 370, the upper part of the housing is hinge-connected and the lower part is connected to the spring shock absorber 360. Thus, if the shielding means spread out from the housing 351 is pressed by a sheet, etc. or the height of the shielding means is too high, the lower part of the housing is pulled or pressed by the spring shock absorber 360 through pushing the shielding means to adjust the height of the shielding means.

Even though a manner for controlling electronic devices described above, that is, the manner for controlling motors and stop switches for controlling electricity supplied to the motors is not shown, it is easily understood that the manner for controlling can be accomplished by a contact switch for controlling the flow of electricity, and a software control for automatically controlling the contact switch. Moreover, this kind of controlling is performed by a control box having a microcomputer therein.

Further, as shown in FIG. 20, as the bed for patient according to the present invention is operated between the legs of the patient with the patient lying down, and the shielding piece 353 to hide the hip and private parts of patient, a disabled patient can pass urine with lying down. At this time, the shielding piece 353 and the shielding piece housing 352 can prevent the patients urine from being splashed to the outside.
